2-Butanone is an organic compound from a family of ketones that are found in trace amounts in nature.
The percentage of
2-butanone was highest (p<0.01) in HO LT, and lowest in AN LT.
External standards of the major flavour components expected to be present in cow milk yoghurt (acetaldehyde, diacetyl, acetone, acetoine and
2-butanone) and vegetable milk yoghurt (Hexylaldehyde/Hexanal) will be obtained for quantification of constituents in further studies.
While, the abundant compounds of the ZZB08 were
2-butanone, 3-hydroxy- (36.82%), acetone (9.12%), 2-thiophenecarboxylic acid, undec-10-enyl ester (8.39%) and linalool (5.28%).
[6] reported that CaO reduced heavy products such as phenol and increased formation of hydrocarbons and light product such as acetaldehyde,
2-butanone, and methanol.
Sodium bisulphate, hydrogen cyanide, acetone,
2-butanone, acetophenone, and cyclohexanone add across the 3,4-double bond of quinazoline.
In earlier unpublished work, sodium lactate was found to contain ketones (acetone on the order of 2.6 mg/L,
2-butanone [methyl ethyl ketone, MEK]) on the order of 0.0380 mg/L, and 2-hexanone (methyl butyl ketone [MBK] on the order of 0.0073 mg/L) based on laboratory analyses and confirmed by vendors.
These contaminants include: acetone, carbon disulfide, ethylbenzene, toluene, total xylenes, methylcyclohexane, and
2-butanone (MEK).
The resin and curing agent were supplied by Resolution Performance Products of Houston, TX 25% of solvent by volume,
2-butanone (99%), was added.
Methyl ethyl ketone (MEK), also known as
2-butanone, is an organic solvent.
The hazardous substances covered in this volume are ammonia;
2-butanone oxime; 2-butenal, dicyclopentadiene; 2,4- dinitrotoluene, 2,6-dinitrotoluene, and 2,4,6-trinitrotoluene; hydrogen fluoride and fluorides; halogenetic anesthetic gases; sulfuric acid; oleum; thiourea; trichloroethene and tetrachloroethene; tryglycidyl isocyanurate; and zirconium.
Vapor-liquid equilibrium in binary systems formed by acetonitrile,
2-butanone and 1,2-dichloroethane.
